The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |
Hazards may include but not limited to: | ground stability (e.g. ground condition or slopes for load placement) overhead hazards (e.g. power lines, service pipes) Insufficient lighting traffic (e.g. pedestrians, vehicles, plant) environmental conditions (e.g. wind, lightning, storms, etc) other specific hazards (e.g. dangerous materials). |
Hazard control measures: | Refers to the systematic process of eliminating or reducing the risk to personnel and property through the application of controls. It includes the application of the hierarchy of control, the six-step preference of control measures to manage and control risk: elimination substitution isolation engineering control measures using safe work practices personal protective equipment. |
Appropriate standards may include: | codes of practice legislation Australian Standards manufacturer's specifications industry standards (where applicable). |
Appropriate personnel may include but not limited to: | riggers doggers. |
Crane | Self-erecting tower crane covers the operation of a crane where the tower structure and boom/jib elements are not disassembled into component sections, which can be transported between sites as a complete unit, and where the erection and dismantling processes are an inherent part of the crane's function. |
Appropriate may include but is not limited to: | crane capabilities environmental conditions (e.g. wind, lightning, storms, etc). |
Communicationmethods may include but are not limited to: | verbal and non-verbal language written instructions signage hand signals listening questioning to confirm understanding appropriate worksite protocol. |
Signage and labels may include but not limited to: | crane data plates/labels load charts crane decals control labels. |
Procedures may include but are not limited to: | manufacturer's guidelines (instructions, specifications or checklists), industry operating procedures workplace procedures (work instructions, operating procedures, checklists). |
Controls may include but not limited to: | luffing levers (where applicable) hoisting and lowering levers slewing levers including brake trolley levers (where applicable). |
Service logbook may include but is not limited to: | any logbook service book history record system where the service and maintenance history is kept. |
Crane safety devices may include but not limited to: | audible and visual warning devices operator restraint devices (where applicable) lights (where applicable). |
Communication equipment may include but not limited to: | two-way radios whistles bells buzzers. NB: where radio communication equipment is used the transmitting frequencies of the equipment must be selected to prevent interference to or from other radio equipment being used in the vicinity of the crane. |
Hazard prevention/control measures may include but are not limited to: | safety tags on electrical switches/isolators power lines are insulated safety observer used inside exclusion zone power disconnected traffic barricades and control pedestrian barricades trench covers movement of obstructions personal protective equipment adequate lighting suitable site for the crane counterweights (ballast). |
Test lift | The load is lifted just clear of the lifting plane to allow for checks to be safely made in consultation with appropriate personnel to ensure that: near capacity loads do not overload the crane loads of unusual shape or weight distribution are correctly slung load measuring equipment can be used to verify the calculated weight of the load all crane equipment is functioning properly adjustments to the slinging can be made in a safe manner. |
Relevant crane movements may include but not limited to: | luffing (where applicable) slewing trolleying hoisting and lowering loads. |
Communication signals may include but not limited to: | stop - hand stop - whistle hoist up - hand hoist up - whistle hoist down - hand hoist down - whistle luff boom down - hand (where applicable) luff boom down - whistle (where applicable) luff boom up - hand (where applicable) luff boom up - whistle (where applicable) trolleying out - hand trolleying out - whistle trolleying in - hand trolleying in - whistle slew left - hand slew left - whistle slew right - hand slew right - whistle. |
Unplanned and/or unsafesituations may include but not limited to: | failure/lose of control e.g. slew brake hoist drum failure of equipment e.g. hydraulic system environmental conditions (e.g. wind, lightning, storms, etc). |
Shut Down may include but not limited to: | boom/jib slewed to clear buildings and structures (where applicable) trolleying hoist block to park position (where applicable) weather vain mode retracting hoist rope&hook block idle engine to stabilise temperature turning off engine isolating power supply (where applicable) remove key from ignition/control panel lock and secure cabin (where applicable). |
